**Please see images for: ( Certificate of Correction ) ** |
A system of compression molding a synthetic wood formulation into a commercially useable synthetic wood component is described. Surprising results are achieved when the dry formulation is placed under heat and pressure. Many different components may be made using the present invention, such as by example, wood-like trim components for the housing construction industry.
